INFLUENCE OF THE COMBINATION DRUG PRESTANS (PERINDOPRIL A, AMLODIPINE) ON MORPHO-FUNCTIONAL PARAMETERS OF ARTERIAL BED IN ESSENTIAL HYPERTENSION

Abstract

Aim. Recently, the problem of endothelial dysfunction is in high interest. It was proved that microcirculatory disorders play main role in development and progression of target organ damage in essential arterial hypertension (EAH). Microcirculatory bed itself should be the target of EAH. Modern antihypertension drugs, despite of normalization of blood pressure (BP), should fulfill the prevention of target organ damage. In our study, the influence was evaluated, of treatment with the fixed combination of perindopril A and amlodipine (Prestans®, “Les Laboratoires Servier”, France) on structural and functional parameters of the heart and vessels. Material and methods . In the study, 30 patients with grade II-III EAH included, mean age 54,12±9,15 y.o., duration of EAH — 12,6 (4;21) years. For the assessment of endothelial function and structural and functional condition of capillary net of a finger skin, photopletysmography were applied and videocapillroscopy, respectively. Results . Therapy with Prestans® led to improvement of functioning of the middle sized vessels and microcirculatory vessels (MC) (increase of occlusion index on MC level from 1,5 to 1,8, p<0,006); on the large vessels level led to phase shift from 6,0 to 10,3 (р<0,00005). There was influence of Prestans® on the parameters characterizing vascular bed remodelling on the levels of cappilars: density of capillary net in the skin at rest (cap/mm 2 ) increased from 47 cap/mm 2 to 51 cap/mm 2 (р<0,00005), and the density of capillar net after venous occlusion test — from 53 cap/mm 2 to 60 cap/mm 2 (р<0,006). Conclusion. Prestans® is a medication of choice not only for AH treatment, but for prevention of target organs damage, that is based on correction of endothelial dysfunction and morphofunctional parameters at the level of MC.
